Gabi is heartbroken over witnessing Josh with his therapist, but is stuck with him on their plane to Australia. Commiserating with fellow traveler Adam, Gabi accepts his offer to pose as his new wife on his honeymoon to Hawaii, since his actual bride Amanda dumped him at the altar. Meanwhile, Yolanda, Elliot, and Alan end up at the same resort and the manager assumes they're a three-person couple.
Josh shows up in Hawaii to find out what Gabi is doing with her fake husband Adam. But Gabi is desperate to escape back to San Francisco, only to have a hurricane trap everyone on the island. Meanwhile, Elliot is angry after he is saved from a life-threatening situation by Yolanda rather than his husband Alan.
Gabi leads Josh to believe she's landed an amazing job with celebrity chef Giada De Laurentiis. But Josh is determined to outsmart Gabi while keeping his own secret. Meanwhile, everyone gathers at Josh's penthouse to celebrate Yolanda's 50th birthday.
Gabi is thrilled when she wins a local cooking contest using a recipe she got from her Aunt Chris. When the contest organizers want to take a picture of Gabi and her aunt, Gabi is forced to go on a search for someone she hasn't seen in years.
Gabi, Sofia, and Yolanda stay over with Josh while their building is treated for termites. But Josh and Gabi are uncomfortable staying together and try to make sense of an awkward situation. Meanwhile, Alan suggests a weekend getaway to cheer up Elliot, but his destination of choice is Josh's penthouse, making it an even more crowded house.
